Abstract
A metal complex solution comprising an organic solvent, and a complex composed of an organic acid salt of at least one metal and an organic amine or organic ketone compound, dissolved in the organic solvent; a photosensitive metal complex solution comprising the metal complex solution, and a photosensitive resin added to the solution; and a method for forming metallic oxide films, using these solutions.
Claims3
A method for forming a ferroelectric or ferromagnetic metallic oxide film, said method comprising the steps of:
- coating a substrate with a ferroelectric or ferromagnetic metal complex solution comprising an organic solvent and a complex dissolved in said organic solvent, said ferroelectric or ferromagnetic metal complex comprising an organic acid salt of at least one ferroelectric or ferromagnetic metal and an organic amine or an organic ketone compound;
- drying the coating thus formed on said substrate to form a ferroelectric or ferromagnetic metal complex film;
- baking the ferroelectric or ferromagnetic metal complex film at 300° C. to 600° C. to obtain a ferroelectric or ferromagnetic metallic oxide film;
- and
- irradiating the ferroelectric or ferromagnetic metallic oxide film with light having a wavelength of not more than 400 nm to increase residual polarization or to decrease coercive force without changing the crystallinity thereof.
